Battery Tesla or OEM Mercedes

For context, I have a first generation Tesla Model S - 2014. It has 215,000-ish miles on it. The battery capacity has gone down by about 10-12%. It still runs and drives like a dream. It's on the original battery.

I've never had any reason to regret my decision in the past 15 months of ownership, and I absolutely love driving it.

As an owner of a 2016 model S (bought new) with 228k miles on it, still on original battery with a range reduction of less than 15% compared to new.

Just replaced mine in my model 3, it lasted about 4.5 years before I get the alert on my app. Had it replaced in less than 20 minutes via mobile service in the app (there was already a tech in the area).

This just happened to me last month on my 2017 C43 on the OEM battery. I guess five years is typical on these newer MB.

2020 SR+ 51K I get about 229 miles at 100%, advertised range was 250 when it was purchased new.

2018 M3P with 54K and it is right at 7%

2019 model 3 SR with 10% loss based on full charge at 52k miles.

Exactly the same issue I am currently facing with a month old GLC300. No resolution yet

I had the same problem. My car was brand new too but was sitting for a bit before it was sold to me. I brought it in to get charged a few times but the message was still coming up and I was definitely driving it enough. Eventually they just changed the battery under warranty.
